Constructor Details

Nio2Endpoint

public Nio2Endpoint()

Method Details

getDeferAccept

public boolean getDeferAccept()

Is deferAccept supported?

Specified by:

getDeferAccept in class AbstractEndpoint<Nio2Channel,AsynchronousSocketChannel>

getKeepAliveCount

public int getKeepAliveCount()

Number of keep-alive sockets.

Returns:

Always returns -1.

bind

public void bind()
          throws Exception

Initialize the endpoint.

Specified by:

bind in class AbstractEndpoint<Nio2Channel,AsynchronousSocketChannel>

Throws:

Exception

startInternal

public void startInternal()
                   throws Exception

Start the NIO2 endpoint, creating acceptor.

Specified by:

startInternal in class AbstractEndpoint<Nio2Channel,AsynchronousSocketChannel>

Throws:

Exception

startAcceptorThread

protected void startAcceptorThread()

Overrides:

startAcceptorThread in class AbstractEndpoint<Nio2Channel,AsynchronousSocketChannel>

resume

public void resume()

Description copied from class: AbstractEndpoint

Resume the endpoint, which will make it start accepting new connections again.

Overrides:

resume in class AbstractEndpoint<Nio2Channel,AsynchronousSocketChannel>

stopInternal

public void stopInternal()

Stop the endpoint. This will cause all processing threads to stop.

Specified by:

stopInternal in class AbstractEndpoint<Nio2Channel,AsynchronousSocketChannel>

unbind

public void unbind()
            throws Exception

Deallocate NIO memory pools, and close server socket.

Overrides:

unbind in class AbstractJsseEndpoint<Nio2Channel,AsynchronousSocketChannel>

Throws:

Exception

doCloseServerSocket

protected void doCloseServerSocket()
                            throws IOException

Description copied from class: AbstractEndpoint

Actually close the server socket but don't perform any other clean-up.

Specified by:

doCloseServerSocket in class AbstractEndpoint<Nio2Channel,AsynchronousSocketChannel>

Throws:

IOException - If an error occurs closing the socket

shutdownExecutor

public void shutdownExecutor()

Overrides:

shutdownExecutor in class AbstractEndpoint<Nio2Channel,AsynchronousSocketChannel>

setSocketOptions

protected boolean setSocketOptions(AsynchronousSocketChannel socket)

Process the specified connection.

Specified by:

setSocketOptions in class AbstractEndpoint<Nio2Channel,AsynchronousSocketChannel>

Parameters:

socket - The socket channel

Returns:

true if the socket was correctly configured and processing may continue, false if the socket needs to be close immediately

destroySocket

protected void destroySocket(AsynchronousSocketChannel socket)

Description copied from class: AbstractEndpoint

Close the socket. This is used when the connector is not in a state which allows processing the socket, or if there was an error which prevented the allocation of the socket wrapper.
